早有文献报道,在许多手术后,特别是心脏直视手术后,出现尺神经损伤并发症。据认为这种神经损伤是由于术中、术后上肢置于不合适的位置所致。 Wadsworth,Williams和Williams比较术中,术后有关保护尺神经的两种位置。病人仰卧位将前臂及手置于手心向下位置时,尺神经受外压的“危险”。而手心向上可使尺小管“通畅”并使尺神经免于受压。心脏手术中采用的第三种姿势,是将前臂置于头部侧上方,这样也可解除尺小管的压力。本文报道35例心脏直视手术中,上肢置于不同位置对尺神经损伤发生率的影响。其研究结果如下。
It has long been reported in the literature that many complications of ulnar nerve injury occur after many operations, especially after open heart surgery. It is believed that this nerve injury is due to intraoperative and postoperative upper limbs placed in an inappropriate position. Wadsworth, Williams and Williams compared intraoperative and postoperative care to protect the ulnar nerve in two positions. Supine position of the patient’s forearm and hand placed in the lower hand position palm, ulnar nerve by external pressure “dangerous.” The palmar upward can make small tube “patency” and the ulnar nerve from compression. The third posture used in heart surgery is to place the forearm above the head, which also relieves the pressure on the ruler. This article reports 35 cases of open heart surgery, upper limbs placed in different positions on the incidence of ulnar nerve injury. The research results are as follows.
